Title: Auxiliary sheet feeder
IPC: G03G15/00
Filed: 1973-01-02
Abstract: Sheet feed apparatus for an automatic copy machine in which a plurality of tray members each support a corresponding stack of sheets of differing characteristic.

Patent ES-413864-A1 (ES)
Title: Record contact spindle
IPC: H05F3/02
Filed: 1973-04-18
Abstract: One type of video disc record reproducing system senses the capacitance between a stylus and the disc record to reconstruct the video information. The stylus includes a thin conductive element electrode and rides on the record, which is rotated at high speeds. The record, which includes a conductive layer covered with a thin dielectric material, is susceptible to accumulating an electric charge. Disposing a pickup device such as a stylus in proximate or contacting relation with such a charged record disc can produce a destructive discharge of the record through the pickup device which results in damage to the stylus. To minimize the occurence of such damage, the disc record is contacted by means which provide a conductive path through the record spindle to a point of reference potential for the system. In one arrangement, the spindle has a slide bar spring biased to be within the periphery of the spindle when the spindle is stationary. Upon rotation of the spindle, the bar extends out of the spindle to contact the record surface. In a further arrangement, a grounding flipper is pivotally mounted in the spindle. The flipper passes through the record hole and is spring biased to bear against the record surface.

Title: Double exposure and double etch technique for producing precision parts from crystallizable photosensitive glass
IPC: G03C5/00
Filed: 1977-12-26
Abstract: A double exposure and double etch technique for producing precision parts from a photosensitive material is described. The process is described in terms of producing an array of ink jet charge electrodes which comprise a series of small through holes on accurately defined centers. The process comprises the steps of exposing the photosensitive material through a mask to develop an undersized through hole and heat treating the photosensitive material to change its characteristics so that an etchable material is produced in the exposed area. The material is then etched to form the undersized through hole which is substantially tapered. The material is then exposed again with a full sized mask including any conductor patterns and the material is again heat treated. The material is again etched and this etching, in the nature of a surface etch, reduces the taper because of the lower etch rate of the unexposed material as compared to the much higher etch rate of the previously unetched tapered material.
